SPECIFICATION forming part of Letters Patent No. 749,139 dated anuary 5, 1904. Application filed July 3, 1903. Serial No. 164,131. (No model.)

T0 at whom it may concern:

Be it known that 1, CHARLES G. Foo'rn, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Dumping Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and tothe figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in wagon-dumping apparatus, and while it will be described in this specification more especially in connection with its use in dumping wagons loaded with sugar-beets it is evident that the material carried by the wagon is of no consequence and has nothing to do with the construction of the apparatus, which remains the" same whether the wagon to be dumped is loaded with beets, other vegetae bles, ore, or other material.

One important feature of my improved apparatusconsists of means for elevating the wagon to any desired height which may be necessary in order to dump its contents into a car or other receptacle. The apparatus is provided with a base,upon which is mounted a tiltable upright frame forming a guide for a vertically-movable platform, upon which the wagon to be dumped is placed. The mechanism for elevating the platform is so constructed that while starting in a horizontal position the platform is gradually inclined as it is moved upwardly. This is accomplished through the instrumentality of a shaft, upon which are mounted drums of different diameters upon which the liftingcables are wound, those connected with one side of the platform being wound upon the larger drums, whereby this side of the platform is raised more rapidly than the other, resulting in tilting the platform to the .desired inclination by the time it is raised to the required height. Provision is also made for tilting the upright frame after the wagon has been elevated, whereby the latter is brought into the proper relative position to dump its contents into a car or other receptacle located at the side of the apparatus.

Simultaneously with the tilting of the frame a chute is automatically thrown outward to guide the beets or other material into the car and the hinged gate of the wagon-body.

opened.

Having briefly outlined my improved construction, as well as the function it, is intended to perform, I will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In thedrawings, Figure 1 is a side elevation of my improved dumping apparatus, the vertically-movable platform and the wagon mounted thereon being shown in two positions, one in full and the other in dotted lines. Fig. 2 is a side view of the same, showing the frame tilted and the other parts in corresponding positions. Fig. 3 is a horizontal section taken through the upright frame looking downwardly on the platform and base. Fig. 4 is an underneath view of the apparatus. Fig. 5 is a view of the vertically-movable platform shown in detail and on a larger scale. Fig. 6 illustrates the platform mounted at right angles to Fig. 3 and with the wagon in place thereon. In this view the mechanism for locking the Wagon in place on the platform is illustrated. Fig. 7 is a top view of the same. Fig. 8 isa detail view of the mechanism for unlocking the hinged gate 7 of the wagon-body. This view is obtained by looking in the direction of the arrow in Fig. l.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a suitable base, upon which are pivoted, as shown at 6, four upwardly-projecting bars 7. The two adjacent bars 7 on each side are connected at the top by parts 8, only one of which is shown in the drawings. The extremities of each part 8 are pivotally connected with the parts 7. Journaled in the base at the left of the upright frame isarock-shaft 9, having cranks 10 at its extremities. These cranks are connected with the lower extremities of two rods 12, whose upper extremities are connected with two bars 7 near the top of said bars. One of the rods 12 is connected by a side rod 13 with a link 14, pivotally connected with the bar 7 of the frame remote from the inclined rods 12. The link 14 is connected at its lower extremity, as shown at 15, with another link 16, whose upper extremity is pivotally connected with a chute 17, the latter being hinged to the frame, as shown at 18. At the point 19 where the link 16is connected with the chute the lower extremity of a rod 20 is also connected with the chute and with the link 16. The upper extremity of the rod 20 is pivotally connected at 21 with a plate 22, slidably mounted on the upper part of a bar 7. There are two rods 20 and two plates 22, one on each side of the machine. (See Fig. 8.) The lower extremity of one of the rods 20 is connected only with the chute, since the links 14 and 16 are only shown on one side of the machine, though they may be used on both sides, if desired. Each plate 22 is slotted, as shown at 23, and slides on a bolt or pin 24, fast in the framebar 7. Upon the upper extremities of the two plates 22 is hung a cross-bar 25 by means of two links 26. This cross-bar is adapted to swing outwardly to allow the latch 27 of the hinged wagon-body gate 28 to pass as the wagon is elevated, after which the cross-bar will swing back into place beneath the outer extremity of the said latch. Then as the frame is tilted to the position shown in Fig. 2 the chute is thrown outwardly to direct the contents of the wagon-body into a car or other receptacle, (not shown,) and the plates 20, with the cross-bar 24, are elevated sulficiently to raise the latch 27 and allow the hinged gate 28 to drop to the dumping position. (See Fig. 2.)

The rock-shaft 9 is operated by a lever 29, provided with a dog or pawl 30, engaging a notch quadrant 31.

The vertically-movable nated 32 and is provided at its four corners with grooved wheels 33, which engage the bars 7 of the upright frame. These bars 7 form tracks for the wheels as the platform 32 is elevated.

The wagon 34 may be locked on the platform in any suitable manner. As shown in the drawings, the platform 32 is provided with an abutment 35, located on the dumping side of the wagon and adapted to prevent the latter from shifting laterally on the platform as the latter is tilted. The wagon is further locked on the platform by hookshaped arms 36. (See Fig. 6.) These arms are made fast to rock-shafts 37, journaled in the platform and provided at their outer extremities with cranks 38. Between the two shafts 37 a third rock-shaft 39 is journaled in the platform and provided with two cranks 40, projecting in opposite directions and respectively connected with the cranks 38 by rods 41. The bent arms 36 are operated by a lever 42, made fast at one extremity to the rock-shaft 39 and provided with a dog or pawl 42, engaging a ratchetquadrant 43. By moving the lever 42 to the dotted-line position the arms 36 are also thrown to the dotted-line position in Fig. 6, whereby they ongage the axles of the wagon-wheels both in platform is desigfront and rear, whereby the wagon is locked from moving either forward or back on the platform. The platform 32 is slotted, as shown at 32, to allow the arms 36 to operate.

As shown in the drawings, the platform 32, with its load, is elevated by four cables, two of which are designated 44 and the other two 45. The cables 45 are connected with two drums 46 and the cables'44 with two smaller drums 47, fast on a shaft 48, journaled in bearings 50, made fast to the bottom or under surface of the base 5. The cables 44 pass from the drums to engagement with pulleys 51, journaled in the base and located in openings 52, formed in the base, whereby the cables are allowed to pass upwardly over pulleys 53, journaled at the upper extremities of the two right-hand bars 7. After passing over the pulleys 53 the cables pass downwardly, their extremities remote from the drums being attached to the platform 32, as shown at 54. The cables 45 pass from their drums in a direction opposite the cables 44 and engage pulleys 55, journaled in the base and located in openings 56. These cables 45 pass upwardly over pulleys 57, jourualed at the upper extremities of the two bars 7 at the left, and thence downwardly to the platform 32, whereby they are connected with eyebolts 58, made fast to the platform.

For the purpose of elevating the platform 32 the shaft 48 may be operated in any suitable manner. As shown in the drawings, a large gear 59 is made fast to the shaft 48 and meshes with a pinion 60, fast on a shaft 61, journaled in the base of the platform'and operated by any suitable power. As the shaft 48 is rotated it is evident that the platform 32 will be elevated and that its left-hand extremity, referring to the drawings, will be raised faster than its opposite edge or extremity, whereby the platform is gradually tilted as it is raised to the position shown by dotted lines in Fig. 1. Then as the crankshaft 9 is turned to the position indicated by the lever 29 in Fig. 2 the upright frame is tilted toward the right, the chute l7 thrown outwardly, and the cross-bar 25 raised to unlatch the hinged gate of the wagon-body, as heretofore explained, allowing the contents of the wagon-body to escape to the chute, whereby they are directed into the car or other receptacle.

The platform 32 is provided with two guidetracks 32, which prevent the wheels of the wagon from shifting laterally in either direction.

The shaft 61 is provided with a fast pulley 61 which is connected with a band-brake 70, operated by means of a lever 71, connected with the rock-shaft 72.

In order to permit the placing of the wagon upon the platform 32, a sort of skid 62 (indicated by dotted lines in Figs. 3 and 7) may be employed. There will be one of these skids at each end of the platform to enable the wagon to enter the platform at one end any suitable manner from the motor or engine (not shown) employed in elevating the platform.

A chain 63 is shown in Fig. 2 to hold the wagon-body in place. This-chain may be secured to the platform at one extremity and hooked into the wagon-body at the opposite extremity.

. Attention is called to the fact that while the term wagon is used in the specification any other vehicle may be employed in connection with my improved apparatus.

Attention is called to the fact that the bars 7 on the right and left hand sides of the apparatus approach each other as they extend upwardly, whereby their upper extremities are closer together than their lower extremities. The degree of this taper is regulated to correspond with the inclination of the Vertically-movable platform 32, since as the said platform increases its inclination during its upward movement the distance between the bars 7 or the tracks which the wheels 33 of the platform engage must grow less in order that the said tracks or bars may fit or maintain their proper position or relation with reference to the track-wheels of the platform.
